CEMEX, S.A.B. de C.V. (NYSE: CX) announced today that CEMEX will terminate withdrawal rights which arise under Rule 14d-7 and Section 14(d)(5) of the Securities Exchange Act of 1934, described in Section 7.3 of the Bidder's Statement if, and on the date that, its Offer to acquire shares of Rinker Group Limited ("Rinker") (ASX: RIN, NYSE ADR: RIN) is declared unconditional.

As previously announced, CEMEX will declare its Offer to be unconditional if CEMEX's aggregate interest in Rinker Shares exceeds 50% on or before June 8, 2007. If CEMEX's aggregate interest in Rinker exceeds 50% on or before May 31, 2007, then on a day that is no earlier than May 18, 2007, CEMEX will waive the 90% minimum acceptance condition, declare the Offer unconditional and such withdrawal rights will lapse. If CEMEX's aggregate interest in Rinker exceeds 50% on a date after May 31, 2007 and on or before June 8, 2007, which will result in an automatic statutory extension of the Offer Period for 14 days after that time, CEMEX will waive the 90% minimum acceptance condition, declare the Offer unconditional and CEMEX will terminate such withdrawal rights on such date. Rinker security holders should withdraw their tenders immediately if their willingness to tender into the Offer would be affected by a waiver of the minimum acceptance condition.
